Foreign trade manager and relevant personnel warmly welcome our customers, and introduced our product which they are interested in detailedly. The peelable coating is designed using water based polyurethane that can be applied to smooth, non-porous surfaces and simply peeled off once dry. All peelable coatings may be applied with wate...
Analysis on the application of waterborne polyurethane (WPU) in coatings Waterborne polyurethane is used in water based wood coatings, which is expected to obtain excellent film hardness, heat resistance and dielectric properties, and good film-forming properties. The higher the degree of microphase separation of aqueous polyurethane,the greater the difference of softening temperature, the better ...
Phenomenon : Part of the water-based paint film from the primer uplift, which contains gas or liquid, showed uneven distribution. Cause 1.When the water-based paint is applied, the dry water-based paint film is exposed to rain. 2.Apply a water-based paint primer to the wet substrate. 3.Water - based paint film is affected by acid - base and heat. Amelioration 1.Considering the gas phase conditions...
Phenomenon: Wood coating water - based varnish after the grain fuzzy, grain color and luster differ, failed to retain the original style of wood. cause 1.Transparent putty transparency is poor or scraping too thick, reduce the clarity of wood grain. 2.Water-based paint storage time is too long, pigment precipitation, on the shallow under the deep operation without mixing evenly, coating film thick...
Common problem of lacquer of waterborne woodwork: varnish besmear film is not level off, burnish is not even Phenomenon : Wood is filled with putty hole processing, after sealing the bottom, coating brush varnish, coating film flatness is low, luster is not uniform. Cause : Hole putty poor quality, loose, solvent absorption. The wood fiber and pith ray on the wood surface are relatively loose. The...
Water - based wood paint common problems: gloss wood paint uneven luster Phenomenon There is light coating on the wood surface, coating film gloss, some areas of low gloss. Cause The wood fiber and pith ray in cork are loose with the growth of growth rings, the base material infiltrates excessively, the coating film increases the pigment volume concentration due to the decrease of the base ma...
Baking performance of water-based glass paint - ask an expert for water-based paint. Question: I would like to ask about the water-based glass baking paint .Water has a boiling point of 100 degrees Celsius, so if you bake it at 140 degrees, it won't boil and bubble up and destroy the film. Right? Response: Water - based paint to balance the evaporation of water and film curing between the relation...
Water-based wood paint runs off oil---Ask a water paint expert Question: Waterborne wood lacquer should run oil to a rainy day only, or brush one day, also can run oil when waiting for the 2nd day to brush again, did especially ugly later . Water-based white paint does not have this problem. The problem ofwater-based varnish is obvious. Answer： Although it is a water-based paint, the film is hydro...
Problem：Some of the materials used in the construction of wood products are plywood and wood chip fiberboard. One of the rubber is the most afraid of water, water paint spray will dissolve the inside of the glue. The effect that USES close lacquer also is not ideal, how should solve? Is it easy to use sinograce chemical raw material solution? thank you . Response:This type of wood is usually ...
Question: Dear expert, I am now eager to develop a new water-based paint mainly for wood. The problem that needs to be solved urgently is the drying time of water-based paint. I want his dry time to be in 30 seconds, can you achieve excuse me, excuse me be colophony its key effect. Response: Hello, the dry time of water - based paint has two concepts commonly."Surface dryness" refers to the basic ...

The film-forming aids for waterborne wood coatings are generally alcohol ether type solvents. The most commonly used filming aids such as diethanol ethers, propylene glycol ethers and N-methylpyrrolidone have high and low boiling points.Water-based wood coatings in the summer construction, the water volatilization is faster, that is, the surface is relatively fast, some of the moisture may be encl...
Defoamer is one of the most difficult additives in waterborne wood coatings to control the balance between defoaming and leveling.The paint liquid will generate bubbles during the application due to agitation .If the bubbles present in the paint are not removed in time, the film will dry and form an unacceptable flaw.The paint also produces air bubbles during production, pumping and filling. Defoa...
Waterborne paint formulation design system - pH regulator Waterborne wood coatings may also need to adjust the pH when necessary.Most emulsions or aqueous dispersions have been adjusted to a pH of 8 to 9 when they are produced, eliminating the need for pH adjusters when making paint.If the pH value is different, add 0.05% to 0.1% of the pH adjuster during the paint making process, and adjust the p...
The adhesion of the paint film is caused by the mutual attraction between the paint and the polar groups on the surface of the coated substrate, and the mutual attraction between the polar groups is based on the premise that the paint is well wetted on the surface of the coated substrate.Since the wet condition of the coating on the surface of the coated substrate depends on the surface tension of...
